Dearest Sister,

First, I would like to congratulate you on your special day. The happiness I feel for you is immeasurable. Words do my emotions no justice. This day is yours to revel in the love all around you. Please try to enjoy today as much as you can.

Often I hear of people too stressed on their wedding day to even enjoy it. This may be a bit difficult as you and I are some of the most stressed out people I know. Take the day as it comes, and don't fret about making all the details perfect. Odds are things will go wrong, and not end up how you originally planned.

This is okay.

What is important, is being present on your special day, so when you look you see happiness instead of stress.

As for the rest of your marriage, that is completely in your control as well. While it is useful to listen to the advice of our parents or our happily married friends, listen to yourself above all. You know your relationship the best. What works for them, may not work for you. Everyone always believes they have the "secret" to a perfect marriage, but nothing is perfect. People have flaws. Relationships have flaws. Take this into account. Absorb all the advice you're given (and I anticipate you getting a lot of advice) and then follow the path you think is right for you and your relationship. You may make some mistakes, but use that as a learning experience.

Lastly, remember I will always be here for you. Though we may not live under the same roof anymore, or see each other as often as we like, you will forever be my big sister. My first best friend. You hold a special place in my heart, and that will never change. When times get rough (and let's be real, they will) just know that I am only a phone call or text away. I'm here if you need to vent, or if you need a shoulder to cry on. I'm here for you through it all.

Good luck and Congratulations on your special day!

Your (first) little sister
